Finite Element Method for Multiphase Flow Instabilities | #Sciencefather #Researcherawards
Introduction The study introduces a comprehensive finite element framework designed to model compressible, turbulent multiphase flows with heat transfer , addressing major limitations in conventional finite volume–based Volume of Fluid (VOF) approaches . By integrating a reconstruction-free VOF formulation with the dynamic Vreman large eddy simulation (LES) turbulence model , the method captures interfacial dynamics more accurately in high-speed two-fluid scenarios. Unlike traditional VOF studies that often omit thermal effects, this framework embeds energy transport directly into the multiphase formulation, enabling simultaneous prediction of flow evolution, turbulence, and heat exchange. Its capability to handle conjugate heat transfer without prescribing interfacial heat fluxes represents a major advancement over finite volume methods, which typically require explicit thermal boundary conditions that reduce accuracy. The framework’s effectiveness is demonstrated through instabil...
